Hazard Assessment

A hazard assessment of the designed API manufacturing process should be performed prior to the design of a standard or other less formal job description document are drafted. Aiming to develop safe, environmentally friendly and cost effective processes, BOC Sciences has the capability, experience and license to use or handle these hazardous chemicals in multiple process.

Our Services

To make it easier and better for researchers, BOC Sciences provides hazard assessment service in a competitive fashion. We have provided a more efficient way to increase the number of new drugs, greatly shorten the R&D cycle, and reduce the development costs.

Prioritization of the hazard assessment

Our teams have established following criteria to be used for prioritization:

  • Higher daily dose taken
  • Long duration of treatment
  • Therapeutic indication
  • Higher number of patients treated
  • Commercial APIs > APIs used for clinical trials
  • API manufactured in multipurpose equipment > dedicated equipment
  • API manufactured in multipurpose equipment exposed to nitrosating agents
  • API > Intermediate > RSM (for companies manufacturing the three categories)
  • APIs still manufactured > APIs no longer manufactured but still on the market
  • APIs sold to markets where risk assessment have already been requested by authorities
  • APIs sold to other markets
  • Knowledge of the likelihood of a risk based on the chemistry of the process (presence of amine, nitro functionalities, nitrosating agents)

We can handle these hazardous chemicals as follows

  • Reducing agents: iron powder, sodium borohydride, potassium borohydride, lithium aluminum hydride
  • Oxidizing agents: hydrogen peroxide, m-phenylene dimethyl ether
  • Highly toxic substances: sodium cyanide, potassium cyanide
  • Highly reactive compounds: dimethyl sulfate, hydrazine hydrate, phosphorus oxychloride, phosphorus trichloride, phosphorus pentachloride, thionyl chloride
  • Explosives: sodium azide, sodium hydride, diazo compounds, azide compounds

Content of the hazard assessment

BOC Sciences fully consider the following possible sources:

  • Raw materials: recovered solvents, nitrosating agents, nitric acid, nitrites, dimethylformamide and/or other materials
  • Manufacturing process and reaction conditions: conditions forming or suppressing nitrosamines must be assessed such as temperature, pH, carbon treatment, chemical reduction or excess of alcohol
  • Purging factors
  • Structural study and potential subsequent degradation of the structural fragments
  • Water
  • Steam, cleaning agents other than solvents, and consumables
  • Nitrogen
  • Primary packaging: particular attention might be paid to the ones with additives such as antistatic packaging (which might contain specific additives) or packaging for liquid APIs by assessing potential interactions between packaging and API
