从China供应商批量进口4-Emc

4-EMC, or 4-ethylmethcathinone, is a synthetic stimulant compound used in analytical research and pharmaceutical development as a reference standard. The material is supplied as a white to off-white crystalline powder with a purity of 99 % as confirmed by HPLC. It is sparingly soluble in water but freely soluble in organic solvents such as methanol and acetonitrile, making it suitable for chromatographic and spectroscopic analysis.

In laboratory settings, 4-EMC is employed as a calibration standard for forensic toxicology and drug testing methodologies. Typical industry specifications include a melting point range of 145 - 148 °C and a residual solvent content below 0.5 % to ensure analytical accuracy. The compound’s stability is maintained under refrigerated storage at 2 - 8 °C, with protection from light and moisture to prevent degradation.

Research institutions and pharmaceutical laboratories source 4-EMC for method development and validation in LC-MS and GC-MS workflows. The material is packaged in amber glass vials or sealed aluminum bags under inert atmosphere to preserve integrity. Buyers negotiate trade terms such as FOB Shanghai or CIF destination port, with MOQs often set at 100 grams for initial orders.

Shanghai Yida Medical Technology Ltd. is headquartered in Room 2613, Unit 4, Building 9 of Huafucheng in Huangmiao, Hefei, Anhui Province, China. The company specializes in the supply of pharmaceutical intermediates and reference standards for research and analytical applications.

The supplier holds an imported-tier classification with a harbor trust tier, indicating a verified but not highly responsive profile. With a response rate of 0.00 and no recorded average response hours, buyers should proactively establish contact to confirm product availability, analytical data, and export compliance.
