Chemical Structure
Description
As a certified reference material (CRM), Benzyl chloroformate-carbonyl-<SUP>13</SUP>C 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.
Benzyl chloroformate-carbonyl-<SUP>13</SUP>C (CAS 1173019-35-6), molecular formula C7[13C]H13ClO2 and molecular weight 177.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Benzyl chloroformate-carbonyl-<SUP>13</SUP>C is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.63 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.
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.
