Hazard Identification

The first step in toxicological assessment — identifying the intrinsic properties of a substance that could pose a risk to patients.

What is Hazard Identification?

Hazard Identification is the initial step in toxicological assessment, involving a thorough review of the intrinsic properties of a pharmaceutical substance — active ingredients, excipients, or impurities — that could cause adverse health effects.

This includes evaluating existing toxicological data, structure-activity relationships (SAR), literature, and regulatory databases to determine the potential for carcinogenicity, mutagenicity, reproductive toxicity, and other hazards before conducting a full risk assessment.

Molecular structure analysis for hazard evaluation
Why it matters

The foundation every risk assessment builds on.

  • Flags carcinogenic, mutagenic, or reproductive hazards before they become late-stage surprises.
  • Draws on structure-activity relationships (SAR) when direct toxicological data is limited.
  • Feeds directly into Exposure Assessment and Toxicological Risk Assessment.
  • Grounded in existing literature and regulatory databases, not guesswork.
What's included

Methodologies we apply

SAR Analysis

Structure-activity relationship modeling when direct data is limited.

Literature & Database Review

Surfacing existing toxicological data and regulatory precedent.

Genotoxicity Screening

Evaluating carcinogenic and mutagenic potential.

Regulatory Data Review

Cross-checking findings against recognized regulatory databases.

Standards we align to

How we assess it

Our process for Hazard Identification

1

Compile Substance Data

Gathering existing data on the active ingredient, excipient, or impurity.

2

Review Literature & SAR

Structure-activity relationships and published literature are assessed.

3

Screen for Key Hazards

Carcinogenicity, mutagenicity, and reproductive toxicity are evaluated.

4

Report Findings

A documented hazard profile is delivered, ready for exposure assessment.

The deliverable

What you receive

A documented hazard profile for each substance assessed.

Clear flags for carcinogenic, mutagenic, or reproductive risks.

A foundation ready to feed your Exposure Assessment and TRA.

Direct access to the toxicologist behind the review.
