Chemical Structure
Description
As a certified reference material (CRM), 2-Methylbenzylzinc chloride 0.5 M in Tetrahydrofuran 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.
2-Methylbenzylzinc chloride 0.5 M in Tetrahydrofuran (CAS 312693-19-9), molecular formula C8H9ClZn and molecular weight 206.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Methylbenzylzinc chloride 0.5 M in Tetrahydrofuran (C8H9ClZn) contains a salt form, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 206.02 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.
