Chemical Structure

tert-Butyl 3,3-difluorocyclobutanecarboxylate CAS 1355070-36-8 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

tert-Butyl 3,3-difluorocyclobutanecarboxylate (CAS 1355070-36-8) is a high-purity analytical reference standard with the molecular formula C9H14F2O2 and a molecular weight of 192.20 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, tert-Butyl 3,3-difluorocyclobutanecarboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), tert-Butyl 3,3-difluorocyclobutanecarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
