Basic Introduction to Di-Tert-Butyl Dicarbonate
Di-tert-butyl dicarbonate (IUPAC Name: Bis(1,1-dimethylethyl) dicarbonate, CAS No. 24424-99-5, commonly known as DIBOC or Boc anhydride) is a low-melting crystalline solid or clear liquid depending on ambient storage temperature. Renowned for its mild reaction conditions and easily removable byproduct gaseous streams (carbon dioxide and tert-butanol), it represents one of the most reliable protecting agents for amino and hydroxyl functionalities in organic synthesis.
As high-precision microfabrication and advanced fine synthesis demand rigorous raw material consistency, Shandong Look Chemical Co., Ltd. supplies stabilized, ultra-clean Di-tert-butyl dicarbonate optimized for sensitive manufacturing streams. Within the specialized domain of electronic chemicals, Di-tert-butyl dicarbonate is widely utilized as a key structural reagent and protective modifier in photoresist chemistry, chemical amplification polymers, and microelectronic substrate coatings. Its low trace-acid background and reliable reactivity ensure minimal structural defects during photolithography polymer formulations and delicate organic semiconductor processes.

Di-Tert-Butyl Dicarbonate Application
Di-tert-butyl dicarbonate’s high selectivity and clean decomposition profile enable diverse applications across high-technology sectors:
A. Electronic Chemicals & Photolithography
In the realm of advanced electronic chemicals, Di-tert-butyl dicarbonate plays an indispensable role:
Chemically Amplified Photoresists: Used as a key t-Boc protecting group precursor in the synthesis of poly(4-hydroxystyrene) derivatives and acrylic polymers used for deep ultraviolet (DUV/EUV) photolithography.
Specialty Semiconductor Polymers: Serves as a precise functional modifier to regulate acid-cleavable solubility profiles in microelectronic dielectric materials and thin-film coatings.
B. Peptide & Pharmaceutical Synthesis
Amine Protection (t-Boc Derivatives): Selectively reacts with primary and secondary amines under mild conditions to yield stable N-t-Boc protected amino acids, peptides, and complex active pharmaceutical ingredients (APIs).
Hydroxyl & Hydroxamic Acid Functionalization: Acts as a mild derivatizing reagent in the synthesis of protected hydroxamates and specialized organic intermediates.
C. Fine Organic Chemistry & Agrochemicals
Heterocyclic Precursors: Facilitates carbonylation and protection steps in the multi-step synthesis of active crop protection agents and advanced specialty chemicals.
Certifications & Regulatory Compliance
To ensure compliant supply chain operations and smooth customs clearance across North America, Europe, and Asia-Pacific regions, our manufacturing and logistical protocols adhere strictly to international safety and quality standards:
ISO 9001:2015 Quality Management System: Standardized synthesis and purification protocols ensuring batch-to-batch consistency and strict impurity control.
ISO 14001:2015 Environmental Management System: Eco-conscious chemical production focused on emission management and sustainable operations.
GHS & SDS Compliance: Fully compliant 16-section Safety Data Sheets aligned with the latest UN GHS revision, supporting safe handling and cross-border transport.
REACH Compliance Support: Complete technical documentation and registration support for seamless import clearance into the European Union.
Dangerous Goods (DG) Packaging Compliance: UN-rated drums and temperature-controlled storage/shipping containers designed for heat-sensitive organic dicarbonates.
At SD Look Chemical, every batch of Di-tert-butyl dicarbonate undergoes rigorous analytical screening prior to release. Our internal testing facilities utilize high-precision analytical instruments to confirm technical specifications against stringent industrial baselines.
Typical Certificate of Analysis (COA) Specifications:
Appearance: Colorless liquid or white low-melting solid (Conforms / Visual Inspection)
Purity / Assay (GC): ≥ 99.0 % (Typical Result: 99.52 % / GC-FID)
Melting Point: 22.0 °C – 24.0 °C (Typical Result: 23.2 °C / Capillary Method)
Moisture Content: ≤ 0.10 % (Typical Result: 0.04 % / Karl Fischer Titration)
Free Acid (as tert-Butanol / Mono-ester): ≤ 0.20 % (Typical Result: 0.08 % / Acid-Base Titration)
Color (APHA / Hazen): ≤ 20 (Typical Result: 10 / Colorimetry)
Trace Metals (Iron/Fe): ≤ 1 ppm (Typical Result: 0.2 ppm / ICP-MS)
Gas Chromatography (GC-FID): Quantifies total active ester assay while strictly limiting residual tert-butanol and light-end volatile byproducts.
Karl Fischer Coulometric Titration: Critical for applications in electronic chemicals, controlling residual moisture prevents premature hydrolysis of dicarbonate bonds during formulation.
ICP-MS Trace Metal Analysis: Monitors micro-level metallic impurities to satisfy strict cleanliness requirements for electronic and semiconductor applications.
Controlled Retention Storage: Samples from every dispatched lot are maintained in climate-controlled archives for 24 months to support post-delivery technical trace verification.
FAQ
A: We supply Standard Industrial Grade (Assay ≥99.0%) and High-Purity Refined Grade (Assay ≥99.5%). For specialized applications in electronic chemicals and microelectronics, we offer custom-tailored batches with tightened limits on moisture, free acid background, and trace metal ions upon technical agreement.
A: Di-tert-butyl dicarbonate has a low melting point (approx. 22–24°C) and can undergo gradual thermal decomposition if exposed to elevated temperatures. We recommend storing sealed containers in a cool, dry, well-ventilated location below 15°C under dry nitrogen blanketing, away from strong acids, bases, and direct heat sources.
A: Yes. We provide sample quantities (100g to 1kg) for laboratory verification and qualification testing. Our standard commercial packaging includes 25kg fiber drums, 200kg steel/HDPE drums, and insulated shipping boxes tailored for temperature-sensitive air or sea transport.
A: As an experienced exporter of fine organic intermediates, we furnish complete shipping documentation including UN-certified dangerous goods packaging, GHS-compliant Safety Data Sheets (SDS), and lot-specific Certificate of Analysis (COA) to guarantee smooth global logistics and customs clearance.
