Di-tert-butyl-dicarbonate
Di-tert-butyl-dicarbonate, also known as Boc2O, is a colorless crystalline solid used primarily as a protecting group reagent in organic synthesis, especially in peptide and pharmaceutical manufacturing. It has a molecular weight of 202.27 g/mol and is stable under dry, cool conditions. The compound reacts selectively with amines to form tert-butyloxycarbonyl derivatives, enabling controlled functional group protection during multi-step syntheses.
The product is supplied as a transparent crystalline solid with a minimum purity of 99%, as stated in the listing. This high purity is critical for applications in pharmaceutical intermediates where trace impurities can affect downstream reactions or regulatory compliance. Typical industrial standards require low levels of residual solvents, water, and decomposition by-products such as tert-butanol and carbon dioxide. Storage under nitrogen or in sealed containers is standard to prevent moisture absorption.
Buyers include pharmaceutical R&D labs, fine chemical manufacturers, and agrochemical producers engaged in peptide synthesis, nucleoside modification, or amine protection. The reagent is used in the synthesis of APIs such as antibiotics, antivirals, and CNS agents. Packaging is not specified; industry norms include 1 kg, 5 kg, or 25 kg HDPE drums with desiccant. No lead time, MOQ, or certification details are confirmed. Buyers must request these directly from the supplier.

Sourcing Di-tert-butyl-dicarbonate from Danyang Jinxiang Chemical Factory - China Import Guide
Before ordering, verify the purity specification and request a Certificate of Analysis with HPLC or GC data showing impurity profiles. Confirm moisture content is below 0.1% and residual solvents are within ICH Q3C limits. Do not accept generic statements like '99% purity' without supporting analytical data. Ensure the supplier can provide batch-specific documentation for regulatory audits.
Confirm Incoterms, lead time, and packaging with the supplier. Standard terms for chemical exports from China may be FOB Shanghai or Ningbo, with payment via LC or 30% T/T advance. Lead times for specialty chemicals typically range from 20 to 40 days. Packaging should be in sealed HDPE drums with desiccant, labeled as UN3265 Class 8. Confirm compliance with IMDG and IATA regulations.
Conduct pre-shipment inspection for container integrity, seal condition, and label accuracy. Request a sample batch for purity and moisture testing before accepting full shipment. Retain a sample for independent lab analysis. Documentation must include SDS, commercial invoice, packing list, and export declaration. Ensure the supplier provides a traceable batch number for each shipment to support GMP compliance.
