Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 137.14 g/mol gives Phenyl carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Phenyl carbamate (CAS 622-46-8), molecular formula C7H7NO2 and molecular weight 137.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Phenyl carbamate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Phenyl carbamate 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.
