7084-11-9 - Uses and synthesis methods

Introduction

1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, abbreviated as EDC hydrochloride, molecular formula: C8H17N3 · HCl, relative molecular mass 191.70, white crystalline powder, Very easy to absorb moisture, solubility in water> 20g/100ml, soluble in ethanol, melting point 110-114 ℃, used as carboxyl activation reagent in amide synthesis, it is also used to activate phosphate ester groups, cross-linking protein and nucleic acid, and preparation of immunoconjugates. The pH range when used is 4.0-6.0, and it is often used in conjunction with N-hydroxysuccinimide (NHS) or N-hydroxythiosuccinimide to improve coupling efficiency.

Preparation

weigh 12ml of carbon disulfide and dissolve it in 100ml of methanol, slowly add 20.4g of N,N'-dimethylpropylene diamine dropwise, control the temperature at 10-15 ℃, generate white solid in the dropwise process, keep the temperature at 10-15 ℃ for 1 hour after dropwise addition, filter, bubble wash with methanol, and obtain 38g of white solid (intermediate 1) with 95% yield.

weigh 38g of the previous product, add 120ml chloroform, control the temperature at 10-15 ℃, add 24.2g of triethylamine, then slowly add 11.1g of ethyl chloroformate dropwise, add dropwise for 1 hour, keep the temperature for 1 hour after dropwise addition, until the organic phase is dissolved, washed, filtered, and dried to obtain the product (intermediate 2).

weigh 12.9g of ethylamine (containing water 70%), add 60ml of chloroform, cool to 10-15 ℃, slowly add intermediate 2 dropwise, keep the temperature for 1 hour after dropping, wash the organic phase with lye with pH = 11-12, dry, decompress and concentrate to obtain 31.6g of oil (intermediate 3), add 0.012gTEBA at 25 ℃, oxidation with 270g of sodium hypochlorite with a mass concentration of 10%, oxidation is completed, extraction is stratified, organic phase is dried, concentrated at 30 ℃ under reduced pressure, solvent is evaporated to dry, EDC25g is obtained by distillation under reduced pressure, and the purity is 99.2%;

weigh 39g of triethylamine hydrochloride, add 100ml of dichloromethane, control at 30 ℃, slowly add EDC obtained by rectification, dissolve and clear first, then precipitate crystals, finish dropping, cool to 5 ℃, precipitate for 1h, filter to obtain 30.56 g1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride with 99.5% purity and 80.4% yield (n, n'-dimethylpropylene diamine meter).
