Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-methoxyphenyl methylcarbamate 3938-28-1 InChI=1/C9H11NO3/c1-10-9(11)13-8-5-3-4-7(6-8)12-2/h3-6H,1-2H3,(H,10,11 phenol, 3-methoxy-, methylcarbamate.
3-methoxyphenyl methylcarbamate 3938-28-1 InChI=1/C9H11NO3/c1-10-9(11)13-8-5-3-4-7(6-8)12-2/h3-6H,1-2H3,(H,10,11 phenol, 3-methoxy-, methylcarbamate (CAS 3938-28-1), molecular formula C9H11NO3 and molecular weight 181.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-methoxyphenyl methylcarbamate 3938-28-1 InChI=1/C9H11NO3/c1-10-9(11)13-8-5-3-4-7(6-8)12-2/h3-6H,1-2H3,(H,10,11 phenol, 3-methoxy-, methylcarbamate (C9H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 181.19 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3-methoxyphenyl methylcarbamate 3938-28-1 InChI=1/C9H11NO3/c1-10-9(11)13-8-5-3-4-7(6-8)12-2/h3-6H,1-2H3,(H,10,11 phenol, 3-methoxy-, methylcarbamate 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.
