Chemical Structure

Chloroformic Acid Impurity 1 CAS 628-50-2 chemical structure

Description

As a certified reference material (CRM), Chloroformic Acid Impurity 1 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.

Chloroformic Acid Impurity 1 (CAS 628-50-2) is a high-purity analytical reference standard with the molecular formula C6H11ClO2 and a molecular weight of 150.60 g/mol.

Structurally, Chloroformic Acid Impurity 1 (C6H11ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 150.60 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
